Soil Cleanup
More than 11,000 tons, or 22 million pounds, of creosote-impacted soil was consolidated onsite and an engineered cap was built to prevent exposure
Air Quality Monitoring and Testing
Union Pacific performed multiple air quality monitoring and vapor intrusion investigations and testing to ensure that no exposure pathway to area residents exists.
Groundwater Sampling
Union Pacific conducted significant and widespread sampling of 120 groundwater monitoring wells both in and outside the site beneath the Greater Fifth Ward area to investigate for potential contamination.
Continued Cleanup, Testing and
Monitoring
Union Pacific continued groundwater testing, creosote removal, and inspections of the remediated areas to ensure protective barrier caps remain in place.
Guided by scientific data collected at the site, Union Pacific has undertaken and overseen a significant cleanup plan to address any historical groundwater and soil issues and to prevent potential exposure to community residents. Union Pacific is seeking to renew its permit from the U.S. Environmental Protection Agency (EPA) and the Texas Commission of Environmental Quality (TCEQ) to continue this 30-year process through the next phase of our approved plan that includes:
Protective Barrier
Installing a large underground physical barrier wall. This wall is recommended by the EPA as best practice to contain the groundwater contamination and prevent future migration offsite.
Creosote Recovery
Expanding measures to recover creosote at and around the site by installing additional recovery wells and utilizing a trailer-mounted vacuum system that can move to different locations.
Groundwater Monitoring
Continuing groundwater monitoring and performing inspections of remediated areas to ensure that adequate protective barriers are in place.
Additional Protective Measures
Implementing additional protective measures to ensure the continued safety of the surrounding community, including the recovery and removal of creosote from impacted groundwater.
Continued Stakeholder Input
Continuing to regularly engage and seek input from neighbors, area residents and other stakeholders to inform our efforts.
